Elscint recently manufactured a vibratory feeding & sorting system for feeding of uranium pallets. The pellets had a diameter of dia 9.74 x 14 mm length. However, for the actual sizes, the diameter varied from dia 9.6 mm to dia 10 mm. Hence, Elscint provided a sorting equipment with two motorized counter rotating rollers to ensure that the incurrect pellets were sorted at an accuracy of 40 microns. The minus and plus pellets were sorted and collected in separate bins. The correct pellets were taken forward in a tube and singulated with the help of an electric actuator so that they would be kept ready for pick up by the customer robot. No pneumatics was to be used and hence Elscint used a 24 V Electric Actuator for the singulator. As the equipment was to be placed in a separate cell with no operator access and hence it was imperative that not a single pellet stayed in the unit and even the last one was removed without any manual intervention. The special bowl manufactured by Elscint ensured this. The uranium pallets being radioactive, it was ensured that no operator interface was required for any maintenance. The pellets also being brittle, it was ensured that their fall in the bowl feeder as well as after sorting was reduced to the maximum extent possible. The electrical panel was housed in a separate control box and kept at a distance of 15 mtrs.
